Ultra-high performance concrete
Ductal is a new material technology that offers ductility, strength, and durability while providing moldable products with a quality surface. Compressive strengths reach up to 30,000 psi (200 MPa) and flexural strengths reach up to 7,000 psi (50 MPa). With Ductal, it is possible to create thinner sections, longer spans, and higher structures, which are lighter, more graceful and innovative in geometry, and have superior durability and impermeability against corrosion, abrasion, and impact.
Ductal provides precasters with opportunities to improve many existing products and to manufacture new lines of products that will compete with stainless steel, cast iron, ceramics, and others. By utilizing its superior properties, Ductal solutions can eliminate passive reinforcing steel and experience reduced global construction costs, formwork, labor, and maintenance, resulting in benefits such as improved construction safety, speed of construction, and extended life.
